In HTM 9.3, the wrong motion information is used for pruning of DV candidate.

Line 4497 in TComDataCU.cpp is if(puhInterDirNeighbours[iCount] == puhInterDirNeighbours[iCnloop] && pcMvFieldNeighbours[iCnloop<<1]==pcMvFieldNeighbours[(iCount<<1)] && pcMvFieldNeighbours[(iCnloop<<1)+1]==pcMvFieldNeighbours[(iCount<<1)+1])

It should be fixed to if(ivCandDir[1] == puhInterDirNeighbours[iCnloop] && pcMvFieldNeighbours[iCnloop<<1]==tmpMV[0] && pcMvFieldNeighbours[(iCnloop<<1)+1]==tmpMV[1])

Condition if( bOnlyIVP && m_pcEncCfg->getUseIVP() ) in function TEncSearch::estIntraPredQT() results in testing else case when getUseIVP() is false, but should test nothing. This only happens for non-CTC cases and only affects encoder optimization.

The bug can be fixed as follows: TEncCu.cpp:

1064a1065
>             Bool bUseIVP = true;
1072a1074
>               bUseIVP = m_pcEncCfg->getUseIVP();
1073a1076,1077
>             if( bUseIVP )
>             {
1106a1111,1113
> #if HHI_DMM4_ENC_I0066
>           }
> #endif

TEncSearch.cpp:

3142,3144
< #if SEPARATE_FLAG_I0085
<       if( bOnlyIVP && m_pcEncCfg->getUseIVP() )
< #else
3146d3142
< #endif

Setting cfg file to encode two views and two depth maps, encoder stops running after encoding the first frame. Error message: Assertion failed: 0, file ..\..\source\App\TAppEncoder\TAppEncTop.cpp, line 1506
